Abstract
When light passes through a subwavelength-scale square hole in a perfect conductor, the flow of elecrtromagnetic energy exhibits a strikingly rich behavior that depends on the geometry of the rectangular hole. We present a detailed calculation and demonstrate that funneling of electromagnetic energy occurs when certain resonance conditions are met.
